Description

  The present invention relates to a heat storage management system for storing heat energy such as waste heat released to the environment in a detachable heat storage container, and storing or transporting the detachable heat storage container to a place where heat energy is needed. is there.

  In recent years, issues such as depletion of fossil fuels, departure from dependence on nuclear power, or destruction of the natural environment and global warming have been taken up, and interest in technologies that effectively use thermal energy released to the environment has increased. Yes. In particular, high-temperature thermal energy released from garbage incineration facilities, power plants, steelworks, various factories, etc. is released into the environment as a large amount of waste heat without being used. Various heat storage technologies have been studied for the purpose of recovering and effectively using the thermal energy released to these environments.

  In general, heat storage technology is classified into two types: direct heat storage using thermal energy such as sensible heat and latent heat of materials, and indirect heat storage using chemical energy. Sensible heat storage in direct heat storage is a method of storing thermal energy in the form of an increase in the temperature of a substance, and is a preferable method from the viewpoint of economy such as ease of handling the heat storage material and simplicity of the apparatus. However, there is a problem that the heat storage density of the substance is small, and heat loss is large in long-distance transfer and long-term heat storage. In addition, latent heat storage in direct heat storage is a method of storing thermal energy in the form of phase change such as substance dissolution, solidification, evaporation, condensation, sublimation, etc., and the heat storage density is larger than sensible heat storage. The temperature of heat dissipation is constant. In addition, there is a problem that heat loss is large in long-distance transfer and long-term heat storage in latent heat storage.

  On the other hand, chemical heat storage in indirect heat storage is a method of storing heat energy in the form of chemical reactions such as heat of adsorption / desorption of substances, heat of fusion, heat of dilution, etc., and the heat storage density is much larger than sensible heat storage and latent heat storage. Become. Moreover, if the substance before and after the chemical reaction is stable, there is almost no heat dissipation loss, and no heat loss occurs during long-distance transfer or long-term heat storage. Furthermore, chemical heat storage also has a chemical heat pump function that can release thermal energy at a temperature different from the heat storage temperature, and in some cases higher than the heat storage temperature. Therefore, chemical heat storage is suitable as a heat storage management system because it can convert thermal energy into a chemical substance and store it for a long time or stably transfer it to a remote place.

  However, in the development and practical application of a heat storage management system, many cases are due to latent heat storage. For example, in the thermal energy supply method according to Patent Document 1 below, the thermal energy is stored in a state where thermal energy is stored in a main thermal storage unit that houses the thermal storage material, but the thermal storage material used for this is a latent heat storage material. The heat storage capsule filled is used. In addition, in the heat storage unit according to Patent Document 2 below, the heat storage material and the heat exchange medium that exchanges heat by direct contact with the heat storage material are stored in a state where heat is stored in the heat storage container. Although it is to be transferred, a latent heat storage material is also used as this heat storage material.

  The heat storage management system using these latent heat storage materials transfers relatively low-temperature heat energy at around 100 ° C. or lower using simple equipment at a short distance. However, as mentioned above, the use of latent heat storage materials has the problem of large heat loss in long-distance transfer and long-term heat storage, and is released from waste incineration facilities, power plants, steelworks, various factories, etc. There is a limit to the effective use of the large amount of waste heat that is released to the environment without being used. In addition, the development of a heat storage management system using chemical heat storage is also desired in order to efficiently use high-temperature waste heat of several hundred degrees that has been difficult to use.

  In the present invention, as a heat storage management system capable of operating efficiently by chemical heat storage, a method of using a substance that generates heat or heat by dehydration or hydration reaction among chemical heat storage materials is desirable. This is because when high-temperature waste heat is stored, a substance that causes a dehydration reaction in that temperature range can be selected and used. On the other hand, when radiating heat, the phase equilibrium between the chemical heat storage material and water vapor can be used. That is, by controlling the temperature and pressure of water vapor that hydrates with the chemical heat storage material, heat can be radiated at an arbitrary temperature different from that during heat storage.

  In these chemical heat storage materials, reaction water (dehydration reaction water) desorbed from the chemical heat storage material in the heat storage stage dehydration reaction is generated as water vapor. This desorption reaction water needs to be excluded from the chemical heat storage material. For example, the dehydration reaction water is removed using a device such as a condenser. On the other hand, in the hydration reaction in the heat release stage, it is necessary to supply water or water vapor as reaction water (hydration reaction water) to the chemical heat storage material. For this purpose, for example, water such as an evaporator is used to evaporate the hydration water and supply it as water vapor to the chemical heat storage material.

  Specifically, a reaction vessel containing a chemical heat storage material is connected to a condenser, and dehydration water generated by the dehydration reaction is guided from the reaction vessel to the condenser and removed. In addition, the reaction vessel enclosing the chemical heat storage material is connected to the evaporator, and hydration reaction water necessary for the hydration reaction is supplied from the evaporator to the reaction vessel.

  In these heat storage management systems, a reaction container enclosing a chemical heat storage material and a condenser and an evaporator connected to the reaction container are loaded on the heat storage container and stored or transferred simultaneously. Here, the reaction container in which the chemical heat storage material is enclosed contributes to the storage or transfer of heat, and when this is mainly stored or transferred, the heat storage density of the entire heat storage container becomes large. On the other hand, the condenser and the evaporator do not contribute to the storage or transfer of heat, and if these are stored or transferred, the heat storage density of the entire heat storage container becomes small. Furthermore, the reaction water of the chemical reaction is generated at a constant molar ratio with respect to the amount of the chemical heat storage material. When the reaction water is stored or transferred, the heat storage density of the entire heat storage container is further reduced. Therefore, in these heat storage management systems, it is preferable to store or transfer only a reaction container having a large heat storage density, and store or transfer a condenser and an evaporator that do not contribute to heat transfer separately.

  For these reasons, in the heat storage management system, when storing or releasing heat, the reaction vessel is connected to a condenser or an evaporator to remove dehydrated reaction water or supply hydrated reaction water. On the other hand, when storing or transferring a heat storage container loaded with a reaction container, the reaction container must be separated from the condenser or the evaporator. Here, when the reaction vessel is separated from the condenser or the evaporator, air may enter from the pipe connection portion. In addition, when the reaction vessel and the condenser or the evaporator are connected, air that has entered from the pipe connection portion is mixed into the reaction vessel enclosing the chemical heat storage material.

  In these heat storage management systems, the chemical heat storage material repeats dehydration and hydration at high temperatures. Substances such as carbon dioxide in the air are known as deterioration factors of chemical heat storage materials. Therefore, when the reaction vessel is disconnected from or connected to the condenser or evaporator, deterioration factors (such as carbon dioxide contained in the air) that have entered from the pipe connection cause deterioration of the chemical heat storage material, resulting in a heat storage function. There was a problem that decreased.

  In view of the above, the present invention addresses the above, and causes deterioration of the chemical heat storage material in the heat storage container at each stage of heat storage in the heat storage container, storage and transfer of the heat storage container, and heat release from the heat storage container. The purpose is to provide a heat storage management system that can ensure stable and efficient heat storage and heat transfer while ensuring a wide temperature range of heat storage temperature and heat radiation temperature without mixing in air containing carbon dioxide And

The heat exchanger 32 supplies a heat quantity Q to the chemical heat storage material 31a in the heat storage stage, and a heat medium flow in which a silicone oil-based heat medium for receiving the heat quantity Q from the chemical heat storage material 31a in the heat release stage circulates. A path 33 is provided.

In the first embodiment, a calcium hydroxide heat storage material is employed as the chemical heat storage material 31a in order to effectively use high-temperature waste heat exceeding 400 ° C. released by the heat supply facility 10. In the calcium hydroxide heat storage material, calcium hydroxide (Ca (OH) ₂ ) changes to calcium oxide (CaO) by a dehydration reaction when supplied with a heat quantity Q. This reaction is an endothermic reaction, and the following formula (1),
Ca (OH) ₂ → CaO + H ₂ O: ΔH = −63.6 kJ / mol (1)
As shown in Figure 3, it appears as a heat storage effect.

On the other hand, when calcium oxide (CaO) is supplied with water, it becomes calcium hydroxide (Ca (OH) ₂ ) by a hydration reaction. This reaction is an exothermic reaction, and the following formula (2),
CaO + H ₂ O → Ca (OH) ₂ : ΔH = + 63.6 kJ / mol (2)
As shown in FIG.

  Thus, in the first embodiment, by adopting the calcium hydroxide heat storage material, it is possible to reversibly and efficiently use the high-temperature waste heat. In addition, in a chemical heat storage material such as a calcium hydroxide-based heat storage material, the reversible reaction between an oxide and a hydroxide may be hindered by the presence of a specific deterioration factor. For example, the chemical heat storage material is deteriorated by carbon dioxide in the air or carbon dioxide dissolved in a minute amount in the reaction water, and the heat storage effect is reduced.

Specifically, if carbon dioxide (CO ₂ ) is present in the process of reversible change between calcium hydroxide (Ca (OH) ₂ ) and calcium oxide (CaO), calcium carbonate (CaCO ₃ ) is generated and reversible. Inhibit. In particular, in a heat storage and heat release reaction that occurs many times at a high temperature, mixing of a small amount of deterioration factors becomes a big problem. Therefore, in the first embodiment, the chemical heat storage material 31a is enclosed in the reaction vessel 31 so that deterioration factors such as carbon dioxide are not mixed from the outside.

  Here, when adopting a calcium hydroxide heat storage material, water is involved as a dehydration reaction and a hydration reaction (see the above formulas (1) and (2)). In the first embodiment, a water vapor sorption / desorption method is adopted in which the structure of the apparatus is relatively simple and water can be supplied to or removed from the chemical heat storage material 31a uniformly. In this method, it is necessary to exclude water vapor generated by the dehydration reaction from the chemical heat storage material 31a. On the other hand, it is necessary to supply water vapor necessary for the hydration reaction to the chemical heat storage material 31a. Therefore, the removable heat storage container 30 of the first embodiment employs an evaporative condenser (described later) that exchanges water vapor with the chemical heat storage material 31a.

  Moreover, in FIG. 3, the heat supply equipment 10 in the heat storage stage (heat demand equipment 20 in the heat radiation stage) includes a heat supply section 11 (heat demand equipment 21 in the heat demand equipment) and a heat exchanger 12 (22 in the heat demand equipment). ), An evaporative condenser 13 (23 for heat demand equipment), and a reaction water tank 14 (24 for heat demand equipment).

  The heat exchanger 12 (22) is for exchanging heat with the heat supply unit 11 (or the heat demand unit 21), and the heat exchanger 12 (22) receives heat from the heat supply unit 11 in the heat storage stage. A heat medium passage 17 (27 in the heat demand facility) is provided in which a silicone oil-based heat medium for receiving Q and supplying a heat quantity Q to the heat demand section 21 in the heat radiation stage circulates.

  The heat medium flow path 17 (27) is connected to and communicated with the heat medium flow path 33 of the detachable heat storage container 30 by two heat medium flow path connection portions 40 and 50, and a liquid between the two heat medium flow paths is formed. The heat medium circulates. The means for circulating the heat medium is not particularly limited. For example, it is preferable to use a heat medium circulation pump (not shown) such as an overflow turbine pump or a canned motor pump.

  An expansion tank (not shown) may be provided in the flow path of the heat medium flow path 17 (27). This expansion tank has a constant pressure in the heat medium flow path 17 (27) when the liquid heat medium circulating in the heat medium flow path 17 (27) repeats expansion and contraction by heat exchange. It is provided to make the flow rate uniform.

  In the first embodiment, the heat medium flow path when the removable heat storage container 30 and the heat supply equipment 10 (heat demand equipment 20) are separated and transferred at the two heat medium flow path connection portions 40 and 50. The connection between 17 (27) and the heat medium flow path 33 and communication are not particularly limited, and any method may be adopted.

The reaction water is removed from or supplied to 31. The structure and capacity of the evaporative condenser 13 (23) are not particularly limited, and may be appropriately selected depending on the type and amount of the corresponding chemical heat storage material 31a, the heat storage temperature, the heat generation temperature, and other conditions.

  In the first embodiment, the evaporative condenser 13 (23) has a heat exchanger (not shown), and circulates cooling water through the heat exchanger during the dehydration reaction of the chemical heat storage material 31a. The water vapor generated by the dehydration reaction is recovered as condensed water.

The structure and capacity of the reaction water tank 14 (24) are not particularly limited, and may be appropriately selected depending on the capacity of the corresponding evaporation condenser 13 (23) and other conditions.

  In the first embodiment, the evaporating condenser 13 (23) and the reaction water tank 14 (24) are included in the heat supply facility 10 (or the heat demand facility 20).

(Details will be described later).

  Here, in the configuration of FIG. 3, the evaporative condenser 13 (23) of the heat supply facility 10 (or the heat demand facility 20) and the reaction vessel 31 of the detachable heat storage vessel 30 are connected by the reaction water flow path connection portion 60. -Explain the state of communication.

  FIG. 4 is a schematic configuration diagram showing connection of the reaction water flow paths in the first embodiment. In the reaction water channel connection part 60, the reaction water channel 13 a (23 a) of the evaporative condenser 13 (23) and the reaction water channel 34 of the reaction vessel 31 are connected and disconnected by the pipe joint 61. Here, the connection means that a pipe between the two reaction water channels is connected, and does not mean that the reaction water flows between the two reaction water channels. On the other hand, the disconnection means disconnection of the pipe connection between the two reaction water flow paths.

  Here, in the heat storage management system according to the first embodiment, the step of storing heat quantity Q generated from the heat supply facility 10 in the detachable heat storage container 30 (step 1), and the detachable heat storage container 30 after heat storage is heated. Step (step 2) for releasing communication / disconnecting from the supply facility 10, step (step 3) for transferring the detachable heat storage container 30 after heat storage to the heat demand facility 20, and a step for transferring the detachable heat storage container 30 after heat transfer to the heat demand facility Step of connecting / communication to 20 (step 4), step of radiating heat quantity Q from the removable heat storage container 30 after heat storage and supplying it to the heat demand facility 20 (step 5), heating the removable heat storage container 30 after heat dissipation Step of releasing communication / disconnection from demand facility 20 (step 6), step of transferring removable heat storage container 30 after heat dissipation to heat supply facility 10 (step 7), and heat of removable heat storage container 30 after transfer Supply Repeating a cycle composed each step of steps (step 8) to connect and communicate with the Bei 10. Hereinafter, these steps will be described.

≪Step 1≫
Step 1 is a step of storing heat quantity Q generated from the heat supply facility 10 in the detachable heat storage container 30. In this heat storage stage, the detachable heat storage container 30 is incorporated in the heat supply equipment 10, and the heat medium flow path 33 of the detachable heat storage container 30 is heated by the heat supply equipment 10 via the heat medium flow path connections 40 and 50. The heat medium flow path 33 and the heat medium flow path 17 are connected to the medium flow path 17, and a liquid heat medium is circulated by the operation of a heat medium circulation pump (not shown) (see FIG. 3).

  In this heat storage stage, the heat quantity Q generated in the heat supply unit 11 is recovered to the heat medium via the heat exchanger 12, and the heat medium circulates through the heat medium flow path 17 and the heat medium flow path 33 to generate heat. It is supplied to the chemical heat storage material 31 a in the reaction vessel 31 via the exchanger 32. As a result, a dehydration reaction of the chemical heat storage material 31 a occurs, and the amount of heat Q is stored in the chemical heat storage material 31 a in the removable heat storage container 30.

  In step 1, the reaction container 31 of the detachable heat storage container 30 is connected to the evaporation condenser 13 of the heat supply facility 10 (see FIG. 3), and the reaction water flow path 34 and the reaction water flow path 13a communicate with each other. . In this heat storage stage, the reaction water channel 34 and the reaction water channel 13a are connected by a pipe joint 61. Further, the valve 63 of the reaction water channel 34 and the valve 62 of the reaction water channel 13a are opened, and the valve 64 of the discharge channel 13b is closed (see FIG. 4). In addition, cooling water circulates in a heat exchanger (not shown) of the evaporative condenser 13.

  In this state, the water vapor generated by the dehydration reaction of the chemical heat storage material 31a moves from the reaction vessel 31 to the evaporative condenser 13 via the reaction water channel 34 and the reaction water channel 13a and is condensed. It is collected in the tank. Here, the water vapor is condensed in the evaporative condenser 13 to become liquid condensed water, whereby the pressure in the evaporative condenser 13 is lowered, and the water vapor in the reaction vessel 31 is sequentially drawn toward the evaporative condenser 13. It is done.

  Here, FIG. 5 is a pressure-temperature diagram regarding the phase equilibrium of the dehydration and hydration reactions of the calcium hydroxide heat storage material. In FIG. 5, since the temperature of the heat supply unit 11 in the first embodiment is 426 ° C., water vapor in equilibrium with the chemical heat storage material 31a (point A in FIG. 5) at 426 ° C. at the same pressure (FIG. 5). The temperature at point B) is 60 ° C., and the temperature of the cooling water circulating in the heat exchanger of the evaporative condenser 13 is set to a temperature lower than 60 ° C. (point b in FIG. 5). Water vapor can be condensed and recovered.

Thus, when the chemical heat storage material 31a of the detachable heat storage container 30 completes the dehydration reaction, the calcium hydroxide (Ca (OH) ₂ ) of the chemical heat storage material 31a changes to calcium oxide (CaO). 1 ends.

≪Step 2≫
Step 2 is a step of releasing the connection and releasing the connection of the removable heat storage container 30 after the heat storage from the heat supply facility 10. In this step 2, the heat medium flow path 33 of the detachable heat storage container 30 and the heat medium flow path 17 of the heat supply facility 10 are disconnected and disconnected at the heat medium flow path connection portions 40 and 50 (details). Is omitted). In parallel with this, the reaction container 31 of the detachable heat storage container 30 and the evaporative condenser 13 of the heat supply facility 10 are disconnected and disconnected at the reaction water flow path connection part 60.

  Here, an operation of separating the reaction container 31 of the detachable heat storage container 30 and the evaporative condenser 13 of the heat supply facility 10 at the reaction water flow path connection portion 60 will be described. First, in a state after the heat storage step (step 1) is completed, the reaction water channel 34 and the reaction water channel 13a are connected by the pipe joint 61. Further, the valve 63 of the reaction water channel 34 and the valve 62 of the reaction water channel 13a are opened, and the valve 64 of the discharge channel 13b is closed.

  In the communication release / connection release operation in Step 2, first, the valve 63 of the reaction water channel 34 and the valve 62 of the reaction water channel 13a are closed. As a result, the reaction water channel 34 and the reaction water channel 13a are released from communication, and the flow of the reaction water is stopped.

  Next, the valve 64 of the discharge channel 13b is opened. As a result, the reaction water flow path (hereinafter referred to as “pipe connection portion 65”) between the valve 62 and the valve 63 is opened to the external environment via the discharge flow path 13b. In this state, air in the external environment enters the pipe connection portion 65, but it is possible for air to enter the reaction vessel 31 and the evaporation condenser 13 by closing the valve 62 and the valve 63. Absent.

  Next, the pipe joint 61 that connects the reaction water flow path 34 and the reaction water flow path 13a is disconnected, and the valve 64 of the discharge flow path 13b is closed. Thus, the detachable heat storage container 30 is disconnected from the heat supply facility 10, and the detachable heat storage container 30 can be transferred to the position of the heat demand facility 20.

≪Step 3≫
Step 3 is a process of transferring the detachable heat storage container 30 after heat storage from the heat supply facility 10 to the heat demand facility 20. The method for transferring the detachable heat storage container 30 is not particularly limited, and may be appropriately selected depending on the capacity and weight of the detachable heat storage container 30, the distance from the heat supply facility 10 to the heat demand facility 20, and the like. For example, in the case of long-distance transfer, a vehicle, a railroad, a ship, or the like may be used. In the case of short distance transfer, for example, storage or transfer in a factory, a lift, an elevator, a conveyor, or the like may be used.

  In any case, in the first embodiment, since the calcium hydroxide heat storage material is adopted as the chemical heat storage material 31a, the safety at the time of transfer is high, and there is almost no heat dissipation loss. No heat loss occurs even during long-term heat storage. Moreover, in this 1st Embodiment, since the evaporative condenser 13 can be separated and transferred from the detachable heat storage container 30, the total weight of the detachable heat storage container 30 is reduced, and efficient heat storage and heat transfer are possible. Can be realized.

≪Step 4≫
Step 4 is a step of connecting and communicating the removable heat storage container 30 after the transfer to the heat demand facility 20. In step 4, the heat medium flow path 33 of the detachable heat storage container 30 and the heat medium flow path 27 of the heat demand facility 20 are connected and communicated at the portions of the heat medium flow path connection portions 40 and 50 (details are omitted). To do). In parallel with this, the reaction vessel 31 of the detachable heat storage vessel 30 and the evaporation condenser 23 of the heat demand facility 20 are connected / communicated at the reaction water flow path connection portion 60.

  Here, an operation of connecting and communicating the reaction vessel 31 of the detachable heat storage vessel 30 and the evaporative condenser 23 of the heat demand facility 20 at the reaction water flow path connection portion 60 will be described. Table 1 shows operations for connecting and communicating the reaction vessel 31 of the detachable heat storage vessel 30 transferred from the heat supply facility 10 to the evaporation condenser 23 of the heat demand facility 20. In Table 1, the connection state of the pipe joint is indicated by ◯, the connection release state of the pipe joint is indicated by ×, the open state of the valve is indicated by ◯, and the closed state of the valve is indicated by ×.

  In Table 1, operation 1 shows the initial state of the reaction water flow path before the removable heat storage container 30 is transferred from the heat supply facility 10 to the heat demand facility 20 and connected to the heat demand facility 20 (see FIG. 4). ).

  In the initial state of the operation 1, the reaction water flow path 34 of the reaction vessel 31 and the reaction water flow path 23a of the evaporative condenser 23 are disconnected at the pipe joint 61. Further, the valve 63 of the reaction water channel 34, the valve 62 of the reaction water channel 23a, and the valve 64 of the discharge channel 23b are closed.

  In the initial state of the operation 1, the chemical heat storage material 31a of the detachable heat storage container 30 is in a state after heat storage, and is calcium oxide (CaO) in the first embodiment. In this state, the connection / communication operation of the reaction water channel 34 of the reaction vessel 31 and the reaction water channel 23a of the evaporative condenser 23 is performed.

  In the connection / communication operation in step 4, first, in operation 2, the reaction water flow path 34 and the reaction water flow path 23 a are connected by the pipe joint 61. As a result, the evaporative condenser 23 is incorporated in the reaction vessel 31 and is a stage before supplying reaction water to the reaction vessel 31.

  Next, in operation 3, high-temperature water or high-temperature steam is circulated in the heat exchanger of the evaporative condenser 23 while maintaining the opening and closing of the valve in the same manner as in operation 2. In this state, the reaction water in the reaction water tank 24 is supplied to the evaporative condenser 23 through the reaction water recovery supply path 24a to generate water vapor.

  In this way, when the water vapor is generated from the evaporative condenser 23 and the pressure of the water vapor becomes equal to or higher than the atmospheric pressure, in the operation 4, the valve 64 of the discharge flow path 23b is opened. In this state, air enters the pipe connection portion 65 and is under the same atmospheric pressure as the external environment.

  Next, in a state where the valve 64 of the discharge channel 23b is opened, in the operation 5, the valve 62 of the reaction water channel 23a is opened. As a result, water vapor generated in the evaporative condenser 23 flows into the pipe connection portion 65 via the reaction water flow path 23a. Since the water vapor is pressurized to atmospheric pressure or higher, the air remaining in the pipe connection portion 65 is pushed out to the external environment through the discharge flow path 23b.

  Thus, even when the reaction vessel 31 and the evaporative condenser 23 communicate with each other and the water vapor of the reaction water flows through the exhaust operation in the pipe connection portion 65 in the operation 5, air is mixed into the reaction vessel 31. There is no. Therefore, a deterioration factor of the chemical heat storage material such as carbon dioxide in the air does not contact the chemical heat storage material, and a stable heat transfer effect can be maintained.

  Next, in the operation 6, when the air in the pipe connection part 65 is excluded, the valve 64 of the discharge flow path 13b is closed. The method for determining the timing at which the air in the pipe connection part 65 is excluded is not particularly limited, and for example, it may be managed at a preset time according to the configuration conditions of the heat storage management system. Alternatively, a water vapor sensor may be disposed on the external environment side in the vicinity of the valve 64 and managed at the stage where the presence of sufficient water vapor is detected.

  Next, in operation 7, the valve 63 of the reaction water channel 34 is opened. As a result, water vapor generated in the evaporative condenser 23 flows into the reaction vessel 31 via the reaction water channel 23a and the reaction water channel 34, and the hydration reaction of the chemical heat storage material 31a starts.

  Before starting the hydration reaction of the chemical heat storage material 31a, the temperature and pressure of the water vapor generated in the evaporative condenser 23 are adjusted, and the heat generation temperature due to the hydration reaction of the chemical heat storage material 31a is set to an arbitrary temperature. be able to. In the pressure-temperature diagram relating to the phase equilibrium of the dehydration reaction and hydration reaction of the calcium hydroxide heat storage material in FIG. 5, the temperature and pressure of the water vapor supplied to the chemical heat storage material 31a are adjusted to bring it into an equilibrium state. The heat generation temperature of a certain chemical heat storage material 31a can be set.

  For example, in FIG. 5, when obtaining heat generation at 368 ° C., the temperature of water vapor (point D in FIG. 5) in equilibrium with the chemical heat storage material 31 a at 368 ° C. (point C in FIG. 5) at the same pressure is 20 By setting the temperature of the hot water circulating in the heat exchanger of the evaporative condenser 23 to a temperature higher than 20 ° C. (point d in FIG. 5), the heat generation of the chemical heat storage material 31a by the hydration reaction by the evaporated water vapor The temperature can be 368 ° C. In the first embodiment, heat storage is performed by adjusting the temperature and pressure of water vapor supplied to the chemical heat storage material 31a using the pressure-temperature diagram of FIG. 5 (higher than point F in FIG. 5). Heat generation at a temperature higher than the hourly temperature of 426 ° C. (point E in FIG. 5, 600 ° C.) can also be exhibited.

≪Step 5≫
Step 5 is a process of dissipating the heat quantity Q from the removable heat storage container 30 after heat storage and supplying it to the heat demand facility 20. In this heat radiation stage, the detachable heat storage container 30 is incorporated in the heat demand facility 20, and the heat medium flow path 33 of the detachable heat storage container 30 is heated by the heat medium flow path connection portions 40 and 50. The heat medium flow path 33 and the heat medium flow path 27 are connected to the medium flow path 27, and a liquid heat medium is circulated by the operation of the heat medium circulation pump (see FIG. 3).

  In this heat release stage, water vapor generated in the evaporative condenser 23 flows into the reaction vessel 31 through the reaction water channel 23a and the reaction water channel 34, and a hydration reaction of the chemical heat storage material 31a is performed. At this time, the heat quantity Q generated in the chemical heat storage material 31a is recovered to the heat medium via the heat exchanger 32, and this heat medium circulates through the heat medium flow path 33 and the heat medium flow path 27, whereby the heat exchanger 22 is recovered. It is supplied to the heat demand part 21 via. Thereby, the heat quantity Q stored in the chemical heat storage material 31 a in the detachable heat storage container 30 is supplied to the heat demand section 21 of the heat demand facility 20.

  In this step 5, the reaction vessel 31 of the detachable heat storage vessel 30 is connected to the evaporation condenser 23 of the heat demand facility 20 (see FIG. 3), and the reaction water channel 34 and the reaction water channel 23a are in communication. . In this heat radiation stage, the reaction water channel 34 and the reaction water channel 23 a are connected by the pipe joint 61. Further, the valve 63 of the reaction water channel 34 and the valve 62 of the reaction water channel 23a are opened, and the valve 64 of the discharge channel 23b is closed (see FIG. 4). In addition, hot water having a predetermined temperature is circulated in a heat exchanger (not shown) of the evaporative condenser 23.

In this way, when the chemical heat storage material 31a of the detachable heat storage container 30 completes the hydration reaction, the calcium oxide (CaO) of the chemical heat storage material 31a changes to calcium hydroxide (Ca (OH) ₂ ). Step 5 ends.

≪Step 6≫
Step 6 is a step of releasing the connection and releasing the connection of the removable heat storage container 30 after the heat radiation from the heat demand facility 20. In Step 6, the same operation as in Step 2 described above is performed, and the heat supply facility 10 in Step 2 is replaced with a heat demand facility 20.

≪Step 7≫
Step 7 is a process of transferring the detachable heat storage container 30 after heat radiation to the heat supply facility 10. In Step 7, the same operation as in Step 3 described above is performed.

≪Step 8≫
Step 8 is a step of connecting and communicating the removable heat storage container 30 after the transfer to the heat supply facility 10. In step 8, the same operation as in step 4 described above is performed, and the heat demanding facility 20 in step 4 is replaced with a heat supply facility 10.

As described above, pure water is used (details will be described later).

  The relationship between the detachable heat storage container 130 and the heat supply facility 110 (or the heat demand facility 120) in the second embodiment is substantially the same as the schematic configuration diagram (see FIG. 3) shown in the first embodiment. However, the second embodiment is different from the first embodiment in the configuration of the reaction water flow path connecting portion 160 (details will be described later).

  Here, the state where the evaporative condenser 113 (123) of the heat supply facility 110 (or the heat demand facility 120) and the reaction vessel 131 of the detachable heat storage vessel 130 are connected and communicated by the reaction water flow path connecting portion 160 will be described. To do.
